Polar Calculation dialog box

Use the elements in the dialog box to modify the parameters of a polar calculation.

Note: For enterprise industry models .

Element

Base line for polar surveying. It is determined by a station P1 and a connection point P2

Click Graphic icon to identify another base line.

Type an Offset value or use the Graphic icon to shift the line.

Type an Azimuth value or use the Azimuth Reverse icon to interchange start and end point.

Point 1/ Point 2

P1: observing station.

P2: connecting point to determine the base line. If you select a poly line, the vertices that are nearest to the click are used.

Easting/ Northing

You can edit the coordinates in the dialog box or use the Graphic icon to select another point.

Offset

Specify the base line with an offset to the selected element.

Azimuth

Azimuth of the base line (angle between base line and north).

Constructed

CP: Coordinates of the calculated point, target point.

Use the Graphic icon to determine the distance and angle of an existing point. This is useful, if you want to calculate another point with delta values.

Distance

Measured distance between station and new point

Angle

Measured angle (direction) to the new point CP (reading from field measurement.

Value/Delta

You can specify the values by an absolute number or by delta values, related to the current value. This is useful if you want to calculate a number of points with the same distances or angles.

Type a delta value and click Calculate. The new value is calculated by adding the delta to the current value. Click Calculate again. The delta is added again.

Longitud. Shift

Enter a longitudinal offset.

Lateral Shift

Enter a lateral offset (rectangular to the P1-CP line).

Base Angle

Measured angle to the base line point P2
